feat: edit permission entries (v1.35.0)

The Permissions page only offered Delete, so changing a role or scope
meant removing the grant and re-adding it from memory.

A permission's id is derived from (subjectType, subject, scope, domain),
so changing any of those is a different record rather than an update. The
new PUT creates the new grant and removes the superseded one in that
order, so an edit can never leave the old grant behind still conferring
access.
